Hi,

I would like to create a single set of test cases for all individuals in 
a generation, and still be able to use multithreaded evaluation. 

Is it possible to do this in an elegant manner?  If I use 
"prepareToEvaluate" then it will be called for each Problem instance 
that is cloned, i.e. once for each thread, and as my test cases are 
probabilistically selected I will end up with a different set of tests 
cases for each thread, which I don't want! 

Any help appreciated,

Thanks

David
